IT Terms
These are the Pages for IT
Bare Metal
In disaster recovery, a bare metal restore is the process of reformatting a computer from scratch after a catastrophic failure. Typically the process involves reinstalling the operating system and software applications and then, if possible, restoring data and settings
Canonical
A computer science term which means the natural or normal state. For instance a canonical file structure means a typical file structure that includes Directories and files in a hierarchy
CIFS
Common Internet File System. Mostly used for sharing files over the LAN. Operations such as Read write delete and rename are supported but the files remain on the remote server.CIFS requires other protocols for such as NetBIOS#NetBIOS over TCP
Denial of Service Attack
A denial-of-service attack (DoS attack) or distributed denial-of-service attack (DDoS attack) is an attempt to make a computer resource unavailable to its intended users. Although the means to carry out, motives for, and targets of a DoS attack may vary, it generally consists of the concerted efforts of a person or people to prevent an Internet site or service from functioning efficiently or at all, temporarily or indefinitely. Perpetrators of DoS attacks typically target sites or services hosted on high-profile web servers such as banks, credit card payment gateways, and even root nameservers
DIA
Dedicated Internet Access. Using a Point to Point circuit. A PtP circuit is a private line between two locations. MPLS is a service between two or more locations that is a modern replacement for IP, ATM and/or Frame Relay. MPLS allows appropriate priority to be given when various types of data are transmitted between the locations; voice, video, application (for example, Citrix) and/or other data services can be accomodated with priorities assigned for suitable handling.
Grid Computing
Like Server Clusters but more loosely couples, heterogeneous and distributed. The World Community Grid is a good example of millions of PC's processing power devoted to computing calcuations
M2M
Machine-to-Machine (M2M) refers to technologies that allow both wireless and wired systems to communicate with other devices of the same ability. M2M uses a device (such as a sensor or meter) to capture an event (such as temperature, inventory level, etc.), which is relayed through a network (wireless, wired or hybrid) to an application (software program), that translates the captured event into meaningful information (for example, items need to be restocked).
MAC Address
A Media Access Control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. MAC addresses are used for numerous network technologies including Ethernet. MAC addresses are most often assigned by the manufacturer of a network interface card (NIC) and are stored in its hardware, the card's read-only memory, or some other firmware mechanism. If assigned by the manufacturer, a MAC address usually encodes the manufacturer's registered identification number and may be referred to as the burned-in address. It may also be known as an Ethernet hardware address (EHA), hardware address or physical address.
MX Record
A mail exchanger record (MX record) is a type of resource record in the Domain Name System that specifies a mail server responsible for accepting email messages on behalf of a recipient's domain and a preference value used to prioritize mail delivery if multiple mail servers are available. The set of MX records of a domain name specifies how email should be routed with the Simple Mail Transfer Protocol
NFC
Near Field Communication devices are shortwave wireless devices that can exchange information at short distances. For instance automated payment, transfer of data with other NFC devices, unlocking doors, etc. This is similar to Bluetooth except that data transfer is over very much smaller distances.
.NET
The .NET Framework is a software framework for Microsoft Windows operating systems. It includes a large library, and it supports several programming languages which allows language interoperability (each language can use code written in other languages). The .NET library is available to all the programming languages that .NET supports
- NAS/SANhttp://www.microsoft.com/net/
- Native Application
NFS
Network File System (NFS) is a network file system protocol originally developed by Sun Microsystems allowing a user on a client computer to access files over a network in a manner similar to how local storage is accessed
NOC
Network operation center. Usually hosted data centers.
PCL
Printer Command Language is a defacto standard developed by HP. In general terms the the higher the PCL number i.e. 6 the greater the number of printing options it has in terms of font rendering, WYSIWYG printing outputs etc.
RMAN
Oracle Recovery Manager RMAN optimizes performance and space consumption during backup with file multiplexing and backup-set compression, and integrates with Oracle Secure Backup and third-party media-management products for tape backup such as Back-Up Exec
Samba
Samba is a free software re-implementation. As of version 3, Samba provides file and print services for various Microsoft Windows clients and can integrate with a Windows Server domain, either as a Primary Domain Controller (PDC) or as a domain member. It can also be part of an Active Directory domain. Samba sets up network shares for chosen Unix directories (including all contained subdirectories).
Samba runs on most Unix and Unix-like systems, such as GNU/Linux
Samba allows file and print sharing between computers running Windows and computers running Unix. It is an implementation of dozens of services and a dozen protocols, including the NetBIOS over TCP/IP (NBT), SMB, CIFS (an enhanced version of SMB), DCE/RPC or more specifically, MSRPC, the Network Neighborhood suite of protocols, a WINS server also known as a NetBIOS Name Server (NBNS), the NT Domain suite of protocols which includes NT Domain Logons, Secure Accounts Manager (SAM) database, Local Security Authority (LSA) service, NT-style printing service (SPOOLSS), NTLM and more recently Active Directory Logon which involves a modified version of Kerberos and a modified version of LDAP. All these services and protocols are frequently incorrectly referred to as just NetBIOS or SMB. The NetBIOS and WINS protocols are deprecated on Windows.
Telnet
Telnet is a computer protocol like http and ftp. Telnet stands for 'telecommunications network', and was built to be form of remote control to manage mainframe computers from distant terminals. Telnet has evolved into a new modern version of remote control called 'SSH', that network administrators use today to manage linux and unix computers from a distance. Another kind of Telnet client is PuTTY
UNC
Universal Naming Convention is used by Microsoft to designate its directory path names. In most cases this is double backslash computer name backslash directory name or file name and so on. i.e.\\computer\directory\file. Compare with Unix or the internet that uses forward slash
XML
XML is a machine readable code similar and simpler than HTML. RSS, SOAP ATOM are all XML based formats. EDI messages are sent via XML to customers and Syncada, etc
